Franconian Line

 ( Tectonics ) 

The Franconian Line () is a geological fault in south-eastern Germany that forms the border between the South German Scarplands in the west and the Fichtel Mountains in the east.

The Franconian Line was formed as part of the Variscan orogenesis and was most active between 100 and 50 million years ago, when the Fichtel, with its blocks of Variscan orogeny granite, pre-Hercynian and Palaeozoic meta were uplifted above its forelands that were later filled with Mesozoic-Tertiary period sediments. The vertical displacement is as least near Wirsberg and in some cases maybe close to .
